I enjoyed reading this thread.
After $7.3M daily trading volume of doge yesterday (9 months after release, when 99.8% of other currencies are long gone) with 200%+ margin against #3 currency (litecoin) - this thread is an evidence of fact some people are really, really bad at predictions.
p.s. watch doge replacing LTC as #2 currency by value. Apparently it's the only one out of "big 3" currencies with high ROI potential. Others barely have any short-term potential.
Of cause, plenty of people are bad in predicting the price. Is many people were good at predicting and making a good financial deals, well, there won't be a losers and a winners.
I doubt that others have short-term potential - I see some altcoins with a long-term potential
